Converting a ball mill from an overflow to a grate discharge can allow an operation to increase plant throughput or reduce the product size which can each contribute to higher revenue before heading into action make sure to consider at least mill power draw mill product mill throughput conversion costs.
Discharge of pebbles finer rock ball scats and slurry from mills and its flow through trommels and into other processing operations has strong impacts on overflow ball mill performance.
For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie.
Grate ball mill grate discharge ball mill is a ball milling machine used to grind various ores and other materials grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate its basic structure and grinding process are basically the same as the overflow type ball mill but the structure of the ore discharge part is different.
Grate discharge ball mill picture beltconveyersnet 1830 dia x 3660 long grate discharge ball mill the two most popular types of ball mills are grate or.
converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end the grate holds the balls inside the mill but allows the slurry to pass through and it is then pumped out of the mill by the pulp lifters this is different to an overflow mill which holds the slurry and balls inside until.

Main technical parameters of wetgrinding overflowdischarge rod mill note 1 the cylinder diameter refers to the internal diameter of the cylindrical section and the cylinder length refers to the effective length of the cylindrical section 2 the weight provided in the table excludes ball mass 3.
2 overflow ball mill overflow ball mill does not have grid plate to accelerate ore discharge due to the fact that the hollow axle diameter at the discharging end is slightly larger than that at the feeding end the slurry in the grinding machine has.
compared with the overflow type ball mill the ore discharge of grid type ball mill is lowlevel forced discharge the pulp surface of the ore discharge port is low the fine ore particles can be discharged in time and the heavy mineral will not be concentrated in the ball mill which greatly reducing the overgrinding phenomenon.
